3. Mains hum - Wikipedia

   en.wikipedia.org/wiki/Mains_hum

   Mains hum, electric hum, cycle hum, or power line hum is a sound associated with alternating current which is twice the frequency of the mains electricity.The fundamental frequency of this sound is usually double that of fundamental 50/60 Hz, i.e., 100/120 Hz, depending on the local power-line frequency.

4. Audio frequency - Wikipedia

   en.wikipedia.org/wiki/Audio_frequency

   An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human.The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch.

5. Utility frequency - Wikipedia

   en.wikipedia.org/wiki/Utility_frequency

   The waveform of 230 V and 50 Hz compared with 120 V and 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.

6. Colors of noise - Wikipedia

   en.wikipedia.org/wiki/Colors_of_noise

   For example, with a white noise audio signal, the range of frequencies between 40 Hz and 60 Hz contains the same amount of sound power as the range between 400 Hz and 420 Hz, since both intervals are 20 Hz wide. Note that spectra are often plotted with a logarithmic frequency axis rather than a linear one, in which case equal physical widths on ...

7. Voice frequency - Wikipedia

   en.wikipedia.org/wiki/Voice_frequency

   In telephony, the usable voice frequency band ranges from approximately 300 to 3400 Hz. [2] It is for this reason that the ultra low frequency band of the electromagnetic spectrum between 300 and 3000 Hz is also referred to as voice frequency, being the electromagnetic energy that represents acoustic energy at baseband.
